Installing W7 on the SSD - new roadblock

I installed the SSD, disconnected the HDD and started the W7 installation from my USB stick version. All went well - loading files, country, language, keyboard, etc. - all that passed. But then i get the message: "Setup was unable to locate a new system partition or an existing system partition ..." So I first thought it was because I had only formatted the drive. I restarted and defined an active partition with Diskpart. Tried to install again - same result.
I think it might be that the W7 installer cannot work with the SSD and needs a driver (from USB stick ot CD). Any more ideas?

Update: Just looked at the OCZ website. There is no specific driver for the SSD. I guess it is considered a standard Sata. So my idea was no good. What now?

Right Rick, That's what I just did. I copied my Vista with Ghost. It works fine on the SSD. Next I have to see whether the Windows7 installer accepts that partition. But first i will play around a little with Vista on the SSD. Ghost copied the 27GB from the HDD over in 12 minutes - pretty fast, isn't it?
